WARP-BEAMING MACHINE.

Specification of Letters Patent.

Application filed January 25, 1915. Serial No. 4,134.

To all whom it may concern:

Be it known that I, ARTHUR L, Rem n TON, a citizen of the United States,residing at lVorcester, in the county of Worcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement inlVarp-Beaming Machines, of which the following is a specification,accompanied by drawings forming a part of the same.

The objects of my present invention are to provide means for producing auniform tension upon the individual strands as they are wound upon awarp beam; for adjusting the tension, and for facilitating thereplenishing of the strand spools. These objects, among others, Iaccomplish by the construction and arrangement of parts ashereinafterdescribed, the novel features being pointed out in theannexed claims.

Referring to the accompanying drawings,

Figure 1 represents a side view of myimproved warp beaming machine' Fig.2 is a side view of a portion of the framework carrying the strandspools.

F ig. 3 is a front view of that portion of the machine represented inside view in Fig. 2.

Fig. 4 is a side view similar to that shown in Fig. 2, but with thedevices for imparting an initial tension to the individual strands intheir inoperative positions, and

Fig. 5 is a rear view of the same portion of the machine shown in Fig.4.

Similar reference characters refer to similar parts throughout thedifferent figures.

Referring to Fig. 1, 1 denotes a framework in which a rotating warpvbeam 2 is supported, the usual means being provided for rotating thebeam, but not shown, as they form no part of my present invention. Theindividual strands which are to form the warp are wound upon the beamside by side and the filled beam is then transferred to a weaving loom.It is extremely desirable that the multiplicity of strands should beuniformly wound upon the beam with a uniform tension applied to thestrands. It is one of the objects of my present invention to providemeans for imparting a uniform tension to the strands of the wound beamand also to accurately control the amount of tension imparted.

According to my present invention, each strand is taken from a strandspool 3, sup- 4: placed in proximity to the rotating warp beam 2, asrepresented in Fig. 1. From the strand spools 3 the strands areconducted through guide bars 5 beneath the rolls 6, 7, and over the roll8, resting by gravity upon the periphery of the rolls 6 and 7. Restingupon the yarn of the strand spools 3 are friction levers 9 held uponsquared sections of shafts 10 which are journaled in the framework ofthe creel. The shafts 10 also carry levers 11 provided with weights 12,attached to the levers 11 by bolts 13. The weights 12mare radiallyadjustable upon the levers 11 by means of slots 14 in the levers. Theweights 12 cause a slight pressure to be exerted upon the yarn of thestrand spools 3 by the free ends of the levers 9. By means of thefriction levers 9 an initial tension is applied to each individualstrand which may be delicately adjusted by the adjustment of the weights12 on the levers 11. The initial tension applied to the individualstrands is very much less than the tension required as the strands arelaid; upon the rotating warp beam 2.

I secure the requisite tension. at the warp beam by multiplying theinitial tension imparted at the strand spools by means of the rolls 6, 7and 8, which cause the initial. tension to be multiplied many times bythe passage of the strands beneath the rolls 6 and 7 over the roll 8 andbetween the rolls 6 and 8 and 8 and 7. The strand spools 3 are looselymounted upon the spindles 15 rigidly held in the framework of the creel4 and at an oblique angle to a horizontal plane, as represented in Fig.3, which maintains the strand spools at the lowest ends of the. spindlesby gravity, thereby permitting the strand spools to be removed from thefree ends of the spindles when the spools have been disengaged from thefriction levers 9.

The disengagement of all the strand spools is simultaneouslyaccomplished by means of a series of rocking shafts 16 which carry arms17 extending beneath the levers 11, so that the rocking of the'shafts 16will raise the arms 17 beneath the levers 11 and rock the shafts 10 toswing the friction levers 9 away from the strand spools. One of theshafts 16 is provided at the rear of the creel with a lever handle 18,Fig. 5, and the shafts 16 are also coupled together by the radial arms19 and 2 by which all the shafts 16 are simultaneously rocked by meansof a single lever handle 18. By swinging the lever handle 18 in thedirection of the arrow 21 all the shafts 16 are rocked to raise the arms17, as shown in Fig. 4, and release by a single movement all thefriction levers D from their engagement with the strand spools. Thelever handle 18 carries a spring actuated latch 22 which engages a notch23 in the latching plate 2% in order to hold the arms 17 in their raisedposition and support the weight of the tension devices. The latch isconnected with one arm of a bell crank 25 arranged to be rocked by thecompression of the bell crank against the end of the lever 18 towithdraw the latch 22 from the notch 23, thereby allowing the shafts 16to rock in the opposite direction until the end of the latch 22 isbrought into contactgvith a shoulder 26 on the latching plate 24. lVhenthe latch engages the notch 28, the lifting arms 17 are held in theirelevated position, supporting the levers 11 and weights 12 and holdingthe levers 9 out of contact with the yarn upon the strand spools 3; theshafts 16 are then held from rotation in either direction. By releasingthe latch from the notch 23, the lifting arms 17 are permitted to dropuntil the end of the latch strikes the shoulder 26,

when the shafts 16 are held from rotating in one direction.

I claim:

1. In a warp winding mechanism, a rotating warp beam for receiving amultiplicity of warp threads, a creel for supporting a strand spool foreach individual strand, means for imparting an initial tension to thestrand as it leaves its strand spool, comprising a rocking shaft, afriction lever carried by said shaft bearing directly upon the strandwound upon the strand spool, a second lever carried by said rockingshaft, and a weight adjustable on said second lever and adapted to holdbygravity said friction lever in contact with the strand on the strandspool, and means for simultane ously rendering all of said frictionlevers in operative.

. 2. In a Warp winding mechanism, a warp beam for receiving amultiplicity of warp threads, a creel for supporting a plurality ofstrand spools, means for imparting an initial tension to each strand,comprising i a rocking shaft, a friction lever arranged to bear againstthe strand wound upon the strand spool, a second gravity lever carriedby said rocking shaft, and means for simultaneously raising all of saidgravity levers and holding them in an inoperative raised position.

3. In a Winding mechanism for winding a plurality of strands fromindividual strand spools, a frame for supporting the strand spools, afriction device for each spool, comprising a rocking shaft j ournaledtransversely to said frame, a friction lever carried by said shaft andarranged to bear against the strand wound upon said strand spool, agravity lever carried by said rocking shaft, a second rocking shaftjournaled longitudinally in said frame and below said transverse shafts,and lifting arms carried by said longitudinal shaft and arranged tosupport said gravity arms when in their raised position.

L In a Winding mechanism for winding a plurality of strands fromindividual strand spools, a tension device for each strand, comprising aframe for the strand spools, short rocking shafts journaled transverselyto said frame, friction levers carried by said shafts, gravity leverscarried by said shafts, a second rocking shaft journaled longitudinallyin said frame and beneath said transverse shafts, lifting arms carriedby said longitudinal shaft for raising said gravity levers, and meansfor locking said longitudinal shaft from movement.
